Ukraine

It's been low for months now. The reduction happens to correlate with no more armored vehicles disappearing from the old Soviet stockpiles. I.e. all that's left is useless scrap.

For the past few years there were regular articles about the stockpiles running out, but I guess that was either about specific locations or vehicle models. I haven't seen any such news articles for quite a while, I think it's because there's nothing new to report. Russia appears to be limited to what they have in active service and to new production.

They're pretty screwed, new production can't keep up with the demands of the frontline. And it won't become easier with Ukraine destroying Russia's finances/oil infrastructure and military complex one drone/cruise missile at a time.
